Evaluate this statement: Gene flow increases the genetic divergence of populations.

Describe three ways that evolution can occur via genetic drift.

Why is genetic drift aptly named? Select True or False for each statement.T/F It causes allele frequencies to drift up or down randomly.T/F It occurs when alleles from one population drift into another.T/F It occurs when mutations drift into a genome.

Evaluate the following statements related to the synthesis of nucleic acids. Select True or False for each statement.T/F Ribonucleotides are added to the 3′ end of a DNA strand.T/F Polymerization of nucleic acids occurs by the formation of phosphodiester bonds.T/F Complementary pairing between sugars is required for copying nucleic acids.T/F Strands in a double helix are synthesized in an antiparallel orientation.

True or false? Gene flow can either increase or decrease the average fitness of a population. Explain.

Add labels to the figure that follows, which illustrates how Mycobacterium tuberculosis evolves when it is exposed to an antibiotic.

What is responsible for the increased stability of DNA compared to RNA?
